1 Answer

Black, Red and yellow triangle in upper right corner of the scrn.

Hello I have a Toshiba 57H81 57 in rear projection TV that is only about 5 years old. Yesturday, A black triangle appeared in the upper right corner of the screen outside of that is a red bar that also is on a 45 degree angle adjasent to the triangle, and finaly outside of that is a yellow bar also on a 45 degree angle, adjasent to the red bar. The rest of the picture looks fine, except the color might be a little off across the top. - I have messed with the convergance and the touch focus, and neither made a difference. The problem occurs on any of the inputs.

- Hope someone can help.

    Thanks for the update. I actually did a lot of research and found that it looks like these convergence IC's go bad a lot for these Toshiba TV's. So I got brave and tore open the TV to confirm which model convergence IC's that I had in my unit. I was looking around inside and shown my flashlight through the screen from behind, and the black triangle was there. Super Cheap Fix. There was some black, anti-reflectice sticky paper on the sides inside the cabinet that had come off in the upper right corner. Stuck it back up and whala - Problem Solved. Lucky Me !!!!

YOU HAVE A CONVERGENCE PROBLEM IC'S WILL NEED TO BE REPLACED. THE FACT THAT THE LINES DID NOT MOVE WHEN YOU TRIED TO ADJUST THEM CONFIRMS IT.

Picture has a green shade


Sounds like your red picture tube is not emitting enough brightness to balance the colors. A temporary solution could be to slightly increase the screen voltage of the red CRT to give a good black and white picture when the color control is turned all the way down. If the set has not been serviced in the last 5 years or so, and you're not ready for a new HDTV set, it may be worthwhile to get a technican to look at it and clean the dust off the lenses and mirror and evaluate whether a picture tube rejuvination might work along with the gray scale tracking adjustments.
